    Selective hydrogenation for industrial 1-hexene purification
    (2005) Brown, Tiffany; Fletcher, Jack; Böhringer, Walter
    Previous reports identified selective catalytic hydrogenation as a possible route to the purification of industrial 1-hexene streams. Even so, reported performance has been poor and, consequently, the principal aim of this study is to adjust operating conditions so as to improve process performance to an industrially interesting level. In particular, the influence of hydrogen excess and competitive adsorbates (CO and ethanol) on overall process performance is evaluated for representative (1,5-hexadiene and 1-hexyne) impurity removal from a 1-hexene stream over a bi-metallic Pd-Ag/titania catalyst.
